Calculate the potential corresponding to the following cell. \mathrm{Pt\,|\,Co^{2+}(2.0\ M), Co^{3+}(0.01\ M)\,\|\,Cr_2O_7^{2-}(4.0\ M), Cr^{3+}(0.5\ M), H^+(1.5\ M)\,|\,Pt} Given; V; V

Answer: (A)

Solution

The cell reaction is \mathrm{6Co^{2+} + Cr_2O_7^{2-} + 14H^+ \to 6Co^{3+} + 2Cr^{3+} + 7H_2O} with n = 6 and V; $Q =
